METAL CARLINE FOR CAR-ROOF FRAMES.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed September 25, 1915. Serial No. 52,693.

a citizen of the United States of America, .residlng at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Metal Carlines for Car-Roof Frames; and I hereby declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in carlines for car-roof-iframes and pertains more especially to a carline made from a rectangular rolled steel plate or sheet pressed into the shape required to form a trough which is long enough to bridge the space between and to extend across the tops of the side plates of a car-roof-frame and has two laterally and outwardly projecting side flanges arranged at opposite sides respectively of the trough and extending along the top and longitudinally of the ably morethan the distance apart, along the central portion of the carline, of the longitudinal edges of-the hereinbefore mentioned flanges to the end of enabling the trough to be adequately seated on the side plates of application of the carline.

Another object is to have said trough not only long enough to render it capable of extending from the outer side of one side plate to the outer side of the other side plate of a car-roof-frame and to have the bottom of the trough terminate in downwardly projecting transverse flanges with which the carline is provided at its ends for overlapping the outer sides of said side plates, but to have the end-portions of the carline so contoured that the hereinbefore mentioned side flanges have their end-portions sloping downwardly toward and extending to the outer extremities of the'bottions of the side flanges materially extend the seats formed by the 'bottoms of the endportions of the trough outwardly beyond the sides of the trough and thereby render the carlme capable of seating still more adequately on the side plates to such an extent that any tendency from any cause to laterally tip the carline is effectually opposed.

Another object is to render a carline of thetype indicated adapted, without any shearing or trimming, to be made from a rectangular rolled steel plate or sheet by pressing the plate or sheet into the shape required to form the carline. v

With these objects in view, and to the end of attaining any. other advantages hereinafter appearing, this invention consists in certain, features of construction and rela tive arrangement of parts hereinafter described, pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is a top plan of a carline embodying my invention and shown applied to the side plates'of a carroof-frame. Fig. 2 is a vertical section on line 2-2, Fig. 1. Fig. 3 is an enlarged view of a portion of Fig. 2. Fig. 4 is a vertical section on line 44, Fig. 3, looking outwardly. Fig. 5 .is a left-hand side elevation relative to Fig. 3. Figs. 3, 4 and 5 are drawn on a larger scale than Figs. 1 and 2.

Referring to Figs. 1 and 2 of said drawings, A and A indicate the two laterally spaced horizontally arranged parallel side plates of a car-roof-frame. Each side plate A is shown consisting of a metal bar and provided at the top thereof with a laterally and inwardly pro ecting substantially horizontally arranged v longitudinally of said side plate, and said side plate is shown provided at the bottom with a laterally and outwardly projecting flange 6. The side plates A are shown connected together by my improved metal carline which comprises a trough B which bridges the space between and is mounted on the top flanges a of the side plates, and said trough extends across said flanges. The car line is provided with two vertically downwardly projecting flanges 7 and 7 which are arranged at opposite ends respectively and transversely of the carline and shown overlapping the outer side of opposite side plates A and A respectively. Each transverse flange 7 therefore conflange a which extends.

stitutes a lateral abutment 'for the outer side of the-adjacent side plate. The trough B extends to the outer sides of the flanges 7 so that any water received by the trough is conductedto theouter sides of said flanges. To cause the bottom of the trough to be adequately seated on the side plates each endportion of the trough and the bottom 8 of said end-portion of the trough (see Fig. 1)

is gradually enlarged in width from a point extending longitudinally and from end to end of the trough. The bottom of the trough extends substantially horizontally inwardly, as at 13, from the' bottom 8 of each gradu ally widened end-portion offthe trough (see Figs. 1 and 2) to a point 1 L approximately central between said end-portion and a point 15 approximately central between the ends of the carline, and upwardly toward the lastmentioned point, and the trough is substantially uniform-in depth between said points, but gradually reduced in depth from the first-mentioned of said points in the direction of said end-portion of the bottom of the trough and more conspicuously but gradually reduced in depth at the outer end of said end-portion of said bottom toward and to the outer extremity of said end-portion of said bottom, and each side flange b is preferably gradually enlarged in width (see Fig. 1) from adjacent the first-mentioned of said oints toward and to said end-portion of the bottom of the trough and thence reduced in width toward and to the outer extremity of said end-portion of said bottom,-as shown in Figs. 1 and 5,

Each end-portion of each side flange b is shown sloping quite steeply, as at 16, over the adjacent side plate toward and to the outer sideof said side plate. verse flange 7 of the carline extends to the longitudinal edges of the side flanges b. Each sloping end-portion 16.of each side flange blterminates in the, adjacent downwardly. projecting transverse flange 7 of the carline, and hence said portion 16 of each side flange hasits lower extremity arranged in line transversely of the trough with the adjacent extremity of the bottom of the trough, and said portion of said side flange terminates therefore at said extremity of said bottom. it will be observed that the Each transw bottom of the trough is widest at the lower extremities of the sloping end-portions 16 of the side flanges b, and that the bottom 8 of each gradually widened end-portion of the trough is not only widest at the outer extremity of said end-portion of the trough, but that the width of said bottom of said end-portion of the trough measures at said extremity considerably more than the distance apart, along the central portion of the carline, of the longitudinal edges of the side flanges b.

A carline embodying the invention hereinbe'fore described has not only great strength andstiflness in its end-portions, but is inexpensively formed, without waste, from a rolled steel plate or sheet of minimum dimensions, and has said end-portions so contoured that the carline is capable of seating on the side plates of a car-roof-frame in such a manner and to such'an extent as to eflectually oppose any tendency from any cause to tip the carline laterally- It will be observed also that by the gradual enlargement in the width of the flanges of the carline from points spaced inwardly from the gradually widened end-portions of the trough toward and to said end-portions of the trough, and by said flanges being widest at the inner ends of the said end-portions of the trough, the carline has adequate strength adjacent (the inner ends of said endportions of the trough. I would also remark that it is not unimportant only to have each end-portion of each of the said flanges of the carline slope downwardly toward and terminate at the outer extremity of theadjacent end-portions of the bottom of the trough, but that the width of said bottom at the lower ends of said end-portions of said flanges of the carline measures more than the distance between the longi-' tudinal edges of said flanges along the central portion of the trough and that the enlarged end-portions ofsaid bottom are wide enough over the laterally and inwardly projecting flanges of the metal side plates to permit the application of the two rivets shown and required to efliciently secure said bottom to said flanges of the side plates, without necessitating the use of more expensive devices, such for instance, as bolts and nuts, for securing the trough at its sides to the side plates.

What I claim is 1. A metal carline comprisin having the end-portions thereo gradually enlarged in width toward their outer extremities, which trough is provided at the top with laterally and outwardly projecting flanges extending longitudinally and from end toend of the trough, each end-portion or each of said flanges sloping toward the outer extremity of the adjacent endortion of the bottom of the trough the said ottom a trough being substantially horizontal from the line, the aforesaid flanges being substantially uniform in width between said points and there being a gradual enlargement in the width of said flanges from the first-mentioned point toward and to the adjacent gradually widened end portion of the trough, and said flanges being widest at the inner ends of the gradually widened endportions of the trough.

2. The combination, with the two laterally spaced metal side plates of a car-roof-frame, said side plates being provided at the top with laterally and inwardly projecting flanges extending longitudinally of said side plates, of a metal carline comprising a trough which bridges the space between the side plates and extends over the aforesaid flange and has the bottom of each end-portion thereof enlarged in Width toward the outer extremity of said end-portion, said trough being provided at the top and externally with laterally and outwardly projecting flanges extending longitudinally and from end to end of the trough, each end-portion of each said flanges of the carline sloping downwardly toward and terminating at the outer extremity of the adjacent end-portion of the bottom of the trough, the width of said bottom at the lower ends of said end-portions of said flanges of the carline measuring more than the distance between the longitudinal edges of said flanges along the central portion of the trough, and the enlarged end-portions of said bottom being riveted to the aforesaid flanges of the side plates.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.

JOSEPH A. COSTELLO.
